Title: Production of cystamine sulfate
Inventor: TSUCHIYA MICHIO
IPC: C07C313/00
Filed: 1982-12-16
Abstract: PURPOSE:An aqueous solution of cystamine sulfate resulting from oxiation of an aqueous solution of cysteamine sulfate is subjected to crystallization using a specific alcohol to enable simple and economical production of high- purity cystamine sulfate in high yield with no formation of by-products. CONSTITUTION:An aqueous solution of cysteamine sulfate resulting from addition of sulfuric acid to a cysteamine aqueous solution is combined with hydrogen peroxide to effect oxidation reaction to form a cystamine sulfate solution. Then, 1-4C lower aliphatic alcohol such as methyl, ethyl, n-propyl or iso- propyl alcohol is added to the solution to effect crystallization of the cystamine sulfate and the product is separated. The aqueous solution of cysteamine sulfate is obtained by neutralizing cysteamine with sulfuric acid in an aqueous medium and the product is free from by-products, because the reaction is carried out in an aqueous medium. Further, the crystallization of the cystamine sulfate can be carried out advantageously under conditions free from by-products and excess of sulfuric acid in high efficiency.
